An interesting report, and thankfully free of giant arachnidae! Let us hope that this situation continues to obtain.
I have a few minor addenda - nothing as dramatic as lost elven civilisations (although given their evident continuity of history, perhaps we are the lost civilisation?) and animate trees, of course!
I proceeded to Kazkan's farm once again, and was made welcome by the good yeoman and his family. I arranged to remain awake all night, meditating in the morning, and was rewarded with sight of some extremely interesting phenomena.
Firstly, and rather as expected, around sunset on the day the expedition set out, I observed three short pulses of light from Entatratashan, aiming up into the sky to the west at an angle of about 30° up from horizontal.
Far more interestingly, that signal provoked a response! Approximately ninety seconds later, three answering pulses came back, lighting up Entatratashan and the area of the bluff immediately around it.
There is no observable point from which this reply could have originated - no mountain, no tower, no floating islands, no dots in the sky.
This suggests one of two possibilities: firstly, that the signalling station is hidden from our eyes via camouflage or, more likely, magic - cloaking an entire building or vessel in a shroud of invisibility is conceptually possible, albeit requiring remarkable magical ability.
Secondly, though, and hugely more fascinating to my mind, is the idea that the Second Station is simply too far away for us to see - perhaps so high above the ground that our eyes are simply unable to perceive it! Elven eyesight is reckoned keen by the standards of mortal races, and I asked my familiar Bartimeus to fly as high as he could manage and use his even more acute visual faculty, but to no avail. We repeated the attempts at various times of day and in variable lighting conditions but at no stage could any hint of a Second Station be observed.
The signals (in both directions) were not repeated the following morning when the "power station" was reactivated, however.
Are these then a "start up" signal between Entatratashan and the Second Station? If so, why no repeat of the signal in the morning? Does Entatratashan build up a "reservoir" of power that persists for a time - in this case, overnight - after the power station is activated?
As usual, we have more questions than answers! Do I recall correctly that we have not yet visited Entatratashan whilst the power is flowing? Fascinated as I am by an unknown Elven culture (did you notice if they had a library, perchance?) I think this might be worth prioritising! At the risk of pushing a pet theory, if - as I contend - the Builders travelled between their various installations via nigh-instantaneous magical sub-dimensional translocation ("teleportation" as the stories have it) Entatratashan seems a likely point for one end of such a gate. The "pulsing" signal may therefore indicate the establishment of an arcane link between it and the putative Second Station. Imagine what secrets might lie within!
I must search the libraries of the Tower of Arcane Wisdom to see if it would be possible to determine the speed of a beam of light and extrapolate therefore the distance between Entatratashan and the Second Station - roughly 45 seconds in either direction, not counting any delay in response time from the Station. Hmm...
In any case I now move to the second part of my report - one equally fascinating, I think, although regrettably even more short of solid answers.
I am pleased to relate that I can vindicate the hearsay testimony of the late Alagos - there is indeed an occasional astronomical phenomenon along the dark band known to Kazkan as the Queen's Road!
A little after midnight on the third night, a faint glimmer appeared at the northern edge of the black path (which you will doubtless recall runs east to west), almost directly overhead. A deep orange-red wisp emerged at the northern edge and slowly over the course of several minutes drifted, branched out and spread across the path. To my uninformed eye it very much resembled smoke, although from what I cannot imagine. It did not quite reach the far side, but faded and flickered and about ten minutes after it first appeared, it was no longer observable.
At its greatest extent this "smoke" covered an area of the sky perhaps the size of an outstretched thumb at arm's length - a couple of degrees, at most.
I have few conjectures to explain this mysterious sight. I presume that it cannot be smoke as we understand the term, since - even if we imagine some colossal volcano, itself not visible for some reason, to produce said smoke, the vapour would not normally glow and be visible from so far away.
I invite your thoughts and hypotheses on the matter!
